Oven Parameters
The
OVEN
menu contains the parameters for programming the oven temperature,
from an initial temperature to a final temperature, using up to three ramps during
the analytical run. It is possible to set a single (isothermal) or multiple ramp
program.
In Main Menu move the cursor until
Oven
is selected. Press
ENTER
to display the
OVEN
menu.

Temperature
On - Off
From 20 °C to 350 °C
in step of 1°C
Set On to display the actual and set point values. Set
the initial temperature in °C at which the oven is set
and conditioned before the GC enters the sampling
phase.
Initial Time
INF
From 0 to 99.99 minutes Set the time in minutes. The oven remains at the
starting temperature after a programmed run has
begun. Setting INF, will cause the following menu
lines to disappear.
Ramp 1
On – Off – INF
From 0.1 to 120 °C/min
in step of 0.1 °C/min Rate for the temperature ramp from Initial Temp to
Final temp 1. Set the rate increment to reach the
temperature set in Final temp 1. Set On to enable a
temperature ramp. Setting INF, the GC performs a
ballistic heating and the ramp duration is zero.
